The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.
I posted already some neat images from Cassini's flyby of Helene last week, and commented on how most of the images from that encounter missed Helene entirely or only caught the moon at one edge of the camera field of view. Here's an example of one of those images.
This one is fresh from the spacecraft! The data were captured yesterday, December 26, by Cassini during its best yet imaging encounter with the small ringmoon Prometheus, and showed up on the Cassini raw images website today.
